我们研究社会信息对公共物品自愿提供的影响。相互竞争的理论预测，其他人的贡献可能会替代或补充自己的贡献。我们证明了社会信息对个人贡献的积极影响，支持了互补性理论。我们发现最具影响力的社会信息来自之前贡献的第 90 到 95 个百分点。此外，我们发现这种影响对于新会员来说很显着，但对于续会会员来说则不那么明显。在最有效的情况下，社交信息可以使捐款增加 12%（13 美元）。这些增加的捐款不会排挤未来的捐款。版权所有 © 作者。期刊汇编 © 英国皇家经济学会 2009 年。
We study the effect of social information on the voluntary provision of public goods. Competing theories predict that others' contributions might be either substitutes or complements to one's own. We demonstrate a positive social information effect on individual contributions, supporting theories of complementarities. We find the most influential level of social information is drawn from the 90th to 95th percentile of previous contributions. We furthermore find the effect to be significant for new members but not for renewing members. In the most effective condition, social information increases contributions by 12% ($13). These increased contributions do not crowd out future contributions. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.
